Oxidation of Alkyl Benzene.

[15] Delphine Compe`re, Christian Marazano, B.C. Alkyl groups are usually fairly resistant to oxidation. However, when they are attached to a benzene ring, they are easily oxidised by an alkaline solution of potassium manganate(VII) (potassium permanganate). H.F. A. Aguadero, J. M. Campos-Martin, S. M.

This is a site where special reactions can take place because it's right next to a benzene and it turns out that regardless of the length of the alkyl benzene side chain. Furthermore, the same three types of processes responsible for the removal of the n-alkyl side chain found to be important in studies of the oxidation of the smaller n-alkyl benzenes were found to be responsible for removal of the n-butyl side chain: 1) abstraction of a hydrogen from the alkyl group, decomposition of the radical and oxidation of the subsequently formed species; 2) displacement of the alkyl group by a radical species—usually an H atom; 3) thermal cleavage (homolysis) of part of the side chain followed by oxidation of the resultant radicals. 5H2O‐H‐Phosphonate‐Catalyzed Intermolecular C—S Bond Formation: Synthesis...

This paper reviews various kinds of catalysts involved in the oxidation of alkyl aromatic and their activity in various conditions and probable mechanism of action where applicable. In the above example, t‐butylbenzene does not contain a benzylic hydrogen and therefore doesn't undergo oxidation.
